NextAuth.js
NextAuth.js is an open source authentication library for JavaScript applications, particularly Next.js, handling sign-in with OAuth providers, email links, credentials and session management. Development stalled after it was renamed Auth.js and its main maintainer left in January 2025, leaving the project effectively unmaintained; Better Auth, a newer commercially backed authentication project, took over stewardship of Auth.js on 22 September 2025 to keep it receiving security patches while steering new users toward Better Auth itself.

Newer version available. NextAuth.js was renamed Auth.js during a long-running v5 beta that began in 2023 and never reached a stable release; its main maintainer left in January 2025, leaving the project effectively unmaintained. On 22 September 2025, Better Auth, a newer commercially backed open source auth project, took over stewardship to keep Auth.js from being fully abandoned, providing security patches but recommending new projects use Better Auth instead.

A good fit for
- Existing projects already using NextAuth.js that don't need to migrate immediately, since security patches continue
- Learning how session-based and OAuth authentication works in a Next.js application
- Small projects that want a free, self-hosted authentication library rather than a managed auth service
Not a good fit for
- New projects starting fresh, where the project's own documentation now recommends Better Auth instead
- Teams that need active feature development, given the project's maintenance has slowed significantly since early 2025
- Anyone wanting a managed, hosted authentication service rather than a self-hosted library, where products like Clerk, Auth0 or WorkOS may fit better

About NextAuth.js
NextAuth.js provides authentication for JavaScript applications, most notably Next.js, supporting sign-in through OAuth providers (Google, GitHub and many others), passwordless email links, and custom credentials, along with session and JWT handling built into the framework's routing conventions.
The project was renamed Auth.js during a version 5 rewrite that began in 2023 but stayed in beta for years without reaching a stable release, and its main maintainer departed in January 2025, leaving development effectively stalled.
On 22 September 2025, Better Auth, a newer, commercially backed open source authentication library, took over stewardship of Auth.js to keep it from being fully abandoned. Auth.js continues to receive security patches, but its documentation now points new users toward Better Auth, positioning it as the practical successor; existing Auth.js users are not forced to migrate.
